iBasso JR KLEE $80 LiMg Single Dynamic

iBasso JR KLEE — Review Summary

Price: $80 Type: Single dynamic-driver IEM with a lithium-magnesium diaphragm

Sound and Performance

The reviewer describes the KLEE as neutral-sounding, clean, and balanced, with especially clear mids and no noticeable bass bleed.

Its bass is punchy, tight, and fast, with satisfying weight and good low-bass extension, but it is not especially elevated or warm. The standout qualities are the extended, crisp, detailed upper mids and treble. Despite the treble energy, the reviewer found it smooth rather than harsh or sibilant.

Strings and female vocals are particular strengths, and vocal clarity is a highlight. The KLEE should suit listeners who want clear mids, controlled bass, and an extended top end. Those seeking a warmer or bass-heavier sound may prefer another IEM.

Design, Fit, and Accessories

The medium-sized stainless-steel shells are available in blue or stainless-steel finishes. They have relatively long nozzles, and the reviewer found them comfortable and secure. Each earpiece has visible red or blue vent screens, and the two-pin connectors sit mostly flush.

The included cable is a strong point, with modular 3.5 mm and 4.4 mm terminations, functional hardware, and red/blue left-right indicators. The reviewer slightly preferred a separate pure-copper cable but considered the stock cable good. A basic carry pouch is also included.

The reviewer particularly liked the included gray ear tips, praising their comfortable combination of a firm inner core and soft outer shape. For listening, however, they used JVC Spiral Dot tips, which they felt helped control any potential harshness or sibilance.

The KLEE is very easy to drive, with 22-ohm impedance and 112 dB sensitivity. It features a double-magnet system and a stated Tesla figure of 1.6, and sounded good from a small, inexpensive digital audio player.

Comparisons

• DUNU Falcon Ultra ($200): The reviewer preferred the KLEE overall. Bass volume was similar, but the KLEE was said to reach lower and provide more treble information and a crisper top end. The reviewer also preferred its timbre for strings and female vocals. The Falcon Ultra has a smaller shell, swappable tuning nozzles, and a darker, less energetic treble presentation that may suit treble-sensitive listeners. The comparison used the Falcon Ultra’s blue nozzle, which the reviewer found best.
• Earlier iBasso 3T-154: The KLEE was described as a major improvement over this older, larger-model iBasso IEM, despite costing less.
• The reviewer notes that some other dynamic-driver IEMs, such as the DUNU Quattro, require considerably more power; the KLEE does not.

Drawbacks and Caveats

• Its relatively neutral, exceptionally clean sound may be less appealing to listeners who want added warmth or bass.
• The treble energy may not suit particularly treble-sensitive listeners, although the reviewer found it smooth and used ear tips to further tame the top end.
• The shell is larger than the Falcon Ultra’s, which may make the Falcon a better fit for smaller ears.
• The included carry pouch is basic.

Verdict

The reviewer strongly recommends the KLEE as an unusually capable $80 single-dynamic IEM, especially for listeners who value vocal clarity, clean mids, tight bass, and extended treble. It was the reviewer’s preferred all-rounder over the more expensive Falcon Ultra, except for listeners who prioritize a smaller shell or darker, gentler treble.
